QDX on 10m FT8


This runs at less than 5W, but has been widely spotted again this afternoon. It would seem the tiny QDX is all that is needed to get around the world. Since the photo was taken, many more stations have spotted me today on 10m FT8.

QRP 10m FT8 TX today

UPDATE 1955z:  
64 stations spotted my QRP 10m FT8 today with the QDX transceiver.

XBM80-2 transceiver webpage

As Jason M0NYW has kindly done a PCB layout and provided the Gerber files, I was hoping to add a link to these on my website, but I cannot create a public link to my Google Drive zip file. Not sure if this is a temporary issue. 

See https://sites.google.com/view/g3xbm4/home/hf-mf-and-lf/homebrew/80m-xbm80-2 .


UPDATE 1700z: 
I think I have solved the problem and the link to Jason's Gerber file is now on the webpage.

At Lode - NOT amateur radio

 


As mentioned earlier, we did a nice walk earlier today.

2m activity contest (UKAC)

This evening is the first Tuesday of the month. The RSGB organised activity contest starts at 1900z. I usually go on for a little while with 2.5W and my big-wheel omni antenna. I usually make 5-10 contacts. FT8 is usually easier for me with my poor voice!

UPDATE 1936z:  After just 3 contacts, I just gave up. Some decent DX, but my voice was exhausted with too much shouting!  If I had more stamina, I am sure I would have had plenty of contacts.

Yaesu FT818

This was introduced in 2018 by Yaesu as a replacement for the FT817. It was a huge disappointment, being more for Yaesu's benefit (to overcome component shortages) than adding any new features. Several times over the years Yaesu could have led the world. 

With the FT817 they "owned" the QRP market, then they gifted it to others. In business terms it was unbelievably stupid. 

I hope they really will launch an SDR QRP rig soon, or they might as well give up. 

Walk - NOT amateur radio

For once, the sun was shining. We did a lovely walk with one of our sons and our grandson.  My wife loves her photos!

Family day




Our son and grandson have been here for a few nights and went to see a cousin and his son today. The first photo is with my wife in our garden. The rest are with our son's cousin and his son.

Spring - NOT amateur radio

For the first time this year, we enjoyed coffee in the garden. 

Although still quite cold (12 deg C) it was sunny and spring like.  There are buds on the trees.

This is our front garden. We had coffee on the bench just out of the photo on the left.
